Application filed December 19, 1905. Serial No.292,45 3- T0 at whom itmay concern;

I Be it known that I, FRANKLIN H. NIcHoLs, a citizen'of the UnitedStates, residing at Chetek, in the county of-Barron and State ofWisconsin, have invented a new and useful Plow, of which the followingis'a specification.-

This invention relates to plows, and especially to that classof'plows'which are known as swivel-plows, and which are provided with aswiveled reversible moldboa'rdwhich may be changed from 'a rightto aleft hand position, and vice versa, at the end of each furrow, thusavoiding the necessity of plowing around the field.

'The present invention has for its object to improve and simplifythe'construction and operation of this class of plows; and with theseand other ends in view, which will readily appear as the nature of theinvention is better understood, the same consists of the improvedconstruction and novel arrange-1 ment and combination of parts, whichwillbe hereinafter fully described, andparticularly pointed out in theclaims. I

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that. changes, alterations, and modifications within 'the scope ofthe invention maybe made when desired.

In said drawings, Figure 1 is an elevation, partly in section, of thelandside of a plow constructed in accordance with the principles of theinvention. Fig. 2 is a rear elevation. Fig. 3is a sectional detail viewtaken on the plane indicated by the line 3 3 in Fig. 2 and'on anenlarged scale. Fig. 4 is a perspective detail view-illustrating thepivotal connection between the handles and the plow frame on an enlargedscale. Fig. 5-is a perspective detail view of a portion of the moldofwhich is secured'a frame comprisingfront and rear standards 2 3, al'and'side 4-,and1a bracket 5, which latter extendsf'rearwardly from therearstandard. The reversible or double 'moldboa'rd 6 has a share 7,,rigidly connected therewith, and said share is pro vided witharearwardly-extending pintle 8', pivoted in a recess 9 atthe frontendlo'f the landside. The moldboard is provided on its under sidefnear'its rear end with a massive brace 10, bifurcated at its inner end, whereit is securely bolted or otherwise suit? ably-fastened to the moldboardand pro vided near its'outer end with a pi'ntle 1 1', jour; naled in arecess 12 in the heel end of the landside with which the "moldboard isthus pivotally connected. A reinforcing rod,1 as

the 6th day of'March, 1 900, I prefer to avail vmyself of a wooden beam1 to the underside 13', preferably connects the brace 10 with a T lug 14upon the under side of the near the front end o'fthe latter.

Pivot'ed upona pin 15 at the rear end of the bracket 5 is a casing 16,in which is mounted a slide 17, having a head 18, which projects througha slot 19in the front sideof the easing. The rear side of the latterisprovided moldb'oard with a slot 20, adjacent to which are'formedflanges 21, between which is pivotallysup-f ported a lever 22,having'ahook-shaped outer end 23, which is adapted-to engage the headportion 18 of the slide 17 so as to restrain the latter'from outwardmovement. .The lever 22 is provided at its inner" endwith a pin24,

which cooperates with the pin15".to"support a spring 25, whereby thelever 22, which, as will be seen, constitutes a latch member, operated.The bracket 5 is connectedwith the standard 3 by an oblie uely-disposedpivot 26, engaging a bearing 27, formed at the convergf ing ends ofthehandles28. Said'handles are securely connected togetherandspacedapart by means of a transverse brace 295 The rear end of theplow-beam is provided with a' downwardly extending obli quely disposedbifurcated bracket 30, which pivotally sup ports a lever 31, one end ofwhich terminatesin an eye 32, engaging the'pin 24 of thelatehlever 22 soas to be operable conjointlywith the latter by the spring 25. The otherend of'the lever 31 is' 'provid'e'dwith a' pin 33-, 'which' extendsthrough a perforation in a;

lever.

guide member 34, connected with the rear end of the plowbeam, and isadapted to engage one ofa plurality of recesses 35 in the brace 29 thatconnects the handles.

The brace member 10, which connects the moldboard with the heel end ofthe landside, is provided with a bracket 36, suitably bolted orotherwise secured thereto and having an aperture 37 pivotally engaging apin 38, extending from the head portion 18 of the slide 17.

The operation of the invention, as thus far described, will be readilyunderstood by those skilled in the art to which it appertains. When themoldboard is in operative position, it is locked by the latch-lever 22,engaging the head 18 of the slide 17, which is pivotally connected withthe moldboard through the medium of the brace 10 of the latter. Bydepressing the inner end of the latch-lever the slide will be releasedand permitted to travel outward in the casing 16, thus permitting themoldboard to swing upon its pivot and to be reversed from a right-handto a lefthand position, or vice versa, it being automatically locked atthe terminal of the movement by means of the spring-actuated latch- Whenthe latter is operated to disengage the slide 17 it also actuates thelever 31 to withdraw the pin 33 from engagement with the recess in thecross-brace 29, connecting the handles. The latter may thus be rocked orswung upon the pivot 26, enabling them to assume a proper and naturalposition for operation.

In plows of this class it is customary to attach the handles rigidly tothe beam, and the movement of the moldboard being usually through an aresomewhat exceeding one hundred and eighty degrees it follows that whenthe moldboard is in operative position the handles will be somewhattilted to one side or to the other. Again, when the plow is used forhillsidework, even if the moldboard swings only through an varc ofexactly one hundred and eighty degrees, the operator will be cramped andwill be compelled either to crowd one of the handles or to walk with onefoot in the furrow and the other on the land. By the herein-describedarrangement of the pivoted handles the position of said handles may beshifted when the moldboard is reversed, and the unlocking of the handlesto permit of their being shifted is accomplished simultaneously with theunlocking of the moldboard, so that the reversal of the plow may beaccomplished speedily and effectively.

In the drawings has been illustrated a clevis member 40 the arms ofwhich are pivotally connected with the plow-beam at 41, one of said armsbeing extended rearwardly and connected with one end of anoperatinglever 42, the rear end of which is adapted. to engage any oneof a plurality of notches 43 in a cross-bar 44, connecting the handles,thus enabling the position of the draft-clevis to be shifted laterally.Bracket arms 45 have also been illustrated as connected with theplow-beam for the purpose of carrying a guide-wheel, which latter,however, is not shown.

This invention, as will be seen from the foregoing, is simple inconstruction, easily manipulated, and it has proven in practice to bethoroughly eflicient for the purposes for which it is designed.

Having thus described. the invention, what is claimed is- 1. A plowhaving a swiveled moldboard, means for supporting the same in operativeposition, a pair of handles disposed upon an oblique pivot, and meansfor securing said handles in operative position.

2. In a plow, a swiveled moldboard movable from a right-hand to aleft-hand position, and vice versa, in combination with a pair ofhandles suitably connected and supported upon a single pivot and movablefrom a right-hand to a left-hand position, and vice versa.

3. A plow-beam, a frame connected with the same and including a pair ofstandards, a landside and a rearward-extending bracket, anobliquely-disposed pin connecting said bracket with the rear standardfrom which it extends, a pair of handle members pivoted upon said pin,and means for retaining said handles in adjusted position.

4. In a plow, a beam, a frame connected therewith and including frontand rear standards, a landside and a bracket extending rearwardly fromthe rear standard a reversible moldboard including a share and a braceconnected pivotally with the front and rear ends of the landside, abracket connected with the brace, a casing connected pivotally with thebracket extending from the rear standard, a slide in said casing havinga head pivotally connected with the bracket upon the moldboard-brace,and a spring-actuated latch-lever connected with the casing and adaptedto engage the head. of the slide movable in said casing.

5. A plowbeam, a frame connected with. said beam and having arearwardly-extending bracket, a moldboard connected pivotally with saidframe, a casing pivoted upon the bracket, a slide movable in said casingand having pivotal connection with the moldboard, a latch-lever pivotedupon the easing and adapted to engage the slide, an ob liquely-disposedpin connecting the bracket with the frame from which it extends, handlespivoted upon said pin, a cross-bar connecting said handles and havingrecesses therein, a lever pivoted upon the plow-beam and having a pinadapted to engage the recesses in the cross-braoethe opposite end ofsaid lever being extended in the path of the 5 latch-lever and Connectedloosely with the latter, and a single spring operating to hold the twolatch-levers in looking position.

In testimony that I claim the foregoing as my oWn I have hereto affixedmy signature in the presence of two Witnesses.
